Paroxysmal ventricular tachycardia

Pathological paroxysmal ventricular tachycardia (PPVT) is commonly referred to as paroxysmal ventricular tachycardia. Paroxysmal ventricular tachycardia is called when the onset time is less than 30 seconds and can be terminated on its own. Common in organic heart disease, but also in severe electrolyte disorders, drug poisoning, and cardiac surgery, very few patients have no organic heart disease. Since this type of ventricular tachycardia usually originates from organic heart disease (especially coronary heart disease myocardial infarction), it is a potentially dangerous single-form VT. Because its ECG characteristics are similar to idiopathic ventricular tachycardia, the two are often difficult to distinguish, but the latter occurs in normal healthy people with good prognosis. Therefore, due to completely different etiology, it is important to identify the two in a timely manner. . Therefore, we named the former "pathological paroxysmal ventricular tachycardia", which can better reflect its essence.
